Abstract (en)
The present invention provides a fundus camera which comprises an illumination optical system (10) for projecting an illumination light to a fundus (Ef) of a subject's eye; photographing devices (6a, 6b) for photographing the fundus (Ef); and light-receiving optical systems (20, 30), which include a focus lens (21) disposed in a light-receiving optical path for focusing the photographing devices (6a, 6b) with respect to the fundus (Ef) and diopter compensation lenses (200, 201) disposed for being inserted into or withdrawn from the light-receiving optical path, for guiding reflected light from the fundus (Ef) to the photographing devices (6a, 6b); and a controlling device (9) for determining whether a feasible focusing range of the focus lens (21) is surpassed; and driving devices (200a, 201a) for inserting the diopter compensation lenses (200, 201) into or withdrawing them from the light-receiving optical path, wherein the controlling device (9) controls the driving devices (200a, 201a) to insert into the light-receiving optical path the diopter compensation lenses (200, 201) with a suitable diopter scale making the focus lens (21) focus feasibly if the feasible focusing range of the focus lens (21) is surpassed.
